- Your own dataset — a JSONL dataset you’ve uploaded, scored with scorers like
exact_matchandcontains. - A curated benchmark — GSM8K, HumanEval, and friends. Benchmarks bring their own data, prompting, and scoring; you only pick a model.
How it works
- Create an eval — a reusable definition: a dataset + scorers, or a benchmark task.
- Start a run — the eval × a model target (
deployment:<id>, a serving deployment). - The eval engine fans samples out concurrently (up to 100 in flight) against your deployment’s serving replicas. Code benchmarks execute each completion in an isolated sandbox.
- Watch progress live; read the aggregate score and drill into per-sample items when it completes.
Quickstart (CLI)
Run GSM8K against a serving deployment — no dataset, no config file:--follow streams progress and prints the score when the run completes:
veri run configs/eval.toml works too):
Quickstart (dashboard)
On the Evaluations page:- Click + Create → Run a benchmark (or pick a dataset).
- Choose the benchmark and a sample limit, then Create.
- In the detail panel, pick a serving deployment and click Run eval.
- Progress updates live; scores appear in the runs table when done.
Quickstart (SDK)
Dataset format
Dataset evals expect JSONL rows with aprompt and a reference field (default label):
prompt is either a plain string or a chat-message array; label is what scorers compare against.
Results
A completed run carries per-scorer aggregates:
Per-sample rows (
items) include the input, the model’s output, the reference label, each scorer’s score, and inference latency.
Model targets
Runs targetdeployment:<id> — a deployment in the serving state. Inference cost is attributed through the deployment’s normal request accounting; there is no separate eval billing.
Targeting a scaled_to_zero deployment triggers its wake, and the run fails immediately with a hint to retry: the engine doesn’t hold eval samples open through a multi-minute GPU cold start. Retry the run once the deployment is back to serving, or pre-warm it first with veri deployments wake <id> (scale to zero).
